No. That operation is built into the OS. It is not a program that you can replace. What you can do is have your program already running before the shutdown occurs, and then respond to the shutdown request by intercepting the WM_QUERYENDSESSION and/or WM_ENDSESSION message. Or else have your program initiate the shutdown in the first place instead of the user clicking on the start menu at all.

I thought it's possible to replace the standard shutdown dialog with three options Stand By, Shutdown and Restart with my application. Something like Task Switch, which replaces the standard Alt+Tab dialog.

If the former, then I can understand wanting to replace/augment the dialog. But if the latter, then why not provide that type of configuration inside your own application completely separately from the OS's dialog? Again, I ask, what EXACTLY are you trying to accomplish? Quote: and that's why I wanted to replace the standard dialog with my application, I thought it would be nice to call my application via Start->Turn Off Computer. Rather than replace the existing dialog altogether, you can try keeping the existing dialog and just alter it directly as needed. Write a DLL that calls the SetWindowsHookEx() function to install a WH_CBT hook into the OS. When the DLL receives a HCBT_ACTIVATE notification, you can check if the specified HWND is the dialog or not, and if so then alter it any way you wish, such as by adding additional controls to it. You can also use a WH_CALLWNDPROC and/or WH_CALLWNDPROCRET hook to respond to messages that are issued for your extra controls.

My application has three radiobuttons (Stand By, Shutdown and Restart) I also have a TEdit control in which user enters desired time to execute selected option (format is HH:MM:SS -> for example shutdown my computer at 19:15:00) If I use timeout does it mean that I don't have to use TTimer control? What I'm trying to do is not to have a shortcut on my desktop and not to call my application by double click on the icon on the desktop or anywhere else, but to call it by clicking on the Start->Turn Off Computer. Altering the dialog seems to be the right way. I have to add TEdit control which will be used for entering time (if it's left empty, action should occur immediately and if not timer should be started). But as you probably guessed I don't have much experience with API functions and installing a hook, the only example I saw is installing a mouse hook ([url]http://www.leunen.com/cbuilder/hook.html)[/url], so I'll try to find some tutorials and search on http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/WindowsUserInterface/Windowing/Hooks.asp , to expand my knowledge. If you have any suggestions or links to examples please tell me. Thank you very much.

Provide your own configuration dialog in your application that teh user can bring up at any time. Once the user's desired time value has been saved, you can have the application continuously monitor the current system time. When the configured system time arrives, call the ExitWindows/Ex() function to perform the desired shutdown operation programmably. Quote: What I'm trying to do is not to have a shortcut on my desktop and not to call my application by double click on the icon on the desktop You could write a service that automatically runs in the background at system startup, continuously monitoring the time. You could then provide a separate .exe or .cpl executable for configuring the service. In the case of the .cpl, since it becomes part of the system's Control Panel, you can make it so only admins can run it, and thus only admins can change the time your shutdown operation is performed. You could also specify admin permisions to the .exe if you want to go that route instead. Quote: or anywhere else, but to call it by clicking on the Start->Turn Off Computer. Why, though? That is not necessary, and it makes things harder not only for you, but for the user as well.
